Hypothermia

In 1812, Napoleon attacked Russia with 453,000 men, but after he withdrew from Moscow, the harsh cold winter reduced his "Grande Armee" to fewer than 10,000 fighting men. The vast majority of Napoleon's soldiers were not killed by the Russians. They died of...

Helmets Save Lives

A study from Imperial College in London shows that increased use of helmets by bicycle riders has markedly reduced head injuries (1). Do you know why woodpeckers don't damage their brains when they peck on wood? Their skulls fit so tightly that they don't allow the...

WHOLE Grains are Better than Any Flour

WHOLE Grains are Better than Any Flour

When grains are processed into flour or cereals, the primary concern is loss of nutrients. This is explained in report #N178, Why Flour is Like Sugar. However, if you grind your own grains or use products that are made from the whole grain without discarding anything, you get all or most of the nutrients of the original grain. But grains that have been broken apart in any way will be digested more quickly. That’s a big disadvantage for diabetics and dieters.

What Makes a Healthful Recipe?

All of my healthful recipes fit into the Modified DASH Diet that Dr. Mirkin recommends for total health (to lower cholesterol and blood pressure, control weight and prevent or control diabetes): Up to 8 servings of WHOLE grains (serving size is 1/2 cup) At least 5...

How Many Miles Cycling Equal Miles Running?

During the cold winter months when snow and ice are on the ground, it’s too dangerous to ride a bike, so many cyclists run instead. The standard comparison is that one mile of running equals four miles of cycling, but that’s lousy science. Although running requires the same amount of energy per mile at any speed (110 calories per mile) , riding is affected by wind resistance so the faster you ride, the more energy you use. So you have to compare running and cycling at different cycling speeds.

Soluble and Insoluble Fiber

Fiber is the indigestible structural material of plants that is found in all fruits, vegetables, whole grains, beans, nuts and other seeds. Before food can be absorbed from your intestines into your bloodstream, it must be broken down into basic building blocks. Since you lack the intestinal enzymes to break down fiber into its building blocks of basic sugars, you do not absorb fiber in your upper intestines. Fiber passes through your intestines into your colon where soluble and insoluble fiber are treated differently by the bacteria in your colon.

How to Cook Whole Grains

Whole grains are easy to cook on the stovetop, just as you would cook rice or pasta. I always cook one pound (2½ cups) of whole grains at a time, since they keep well — refrigerated or frozen. Leftovers can be reheated in a microwave or used in salads. I make my own “instant grains” by packaging ½-1 cup portions in baggies and storing them in the freezer. They take a minute or less to thaw in the microwave.

How to Walk Faster

To become fit you need to exercise vigorously enough to increase your heart rate by at least 20 beats a minute. Walking slowly doesn’t make you fit.

Ankle Weights Won’t Help You to Run Faster

Ankle weights do not help you run faster or jump higher. To run fast in competition, you have to run fast in practice. Ankle weights slow you down because they interfere with your coordination and make you work much harder to raise your knees. To jump higher, you have...
